Avoid duplicate destination cells when using a spatial decomp in chunked-rwg #498

Closed bekozi closed 4 years ago

In special cases, duplicate destination cells will appear in a merged weight file. This is caused by split polygons used in the spatial decomposition touching center coordinates in the destination grid.
